SPECIFICATION forming part of Letters Patent No. 377,368, dated February '7, 1888.

Application filed November 15,1887. Serial No. 255,186.

To @ZZ w/wm, it may concern:

De it known that I, CHARLES Brunori, a citizen of the United States, residing-at Cincinnati, Hamilton county, Ohio, have invented newand useful Improvementsin Bed-Bottoms, oi' which the following is a specification.

My invention relates to spring-beds, and is in the nature of an improvement upon Letters Patent No. 364,469, granted to me June 7, 1887. In said patent I described a bed bottom or frame having elevated and fixed head and foot rails and intervening movable side rails supported upon and by pivoted braces secured to cross-braces of the main frame intermediate between thehead and foot rails, the

whole combined with an elastic web secured to the head, foot, and side rails. As thus construeted the weight oi" a body upon or near one of the side rails, in depressing the latter, was resisted by the elastic tension of the web, owing to the pivotal angle of the supportingbraces. In such construction the intervening cross-rails of the frame are found to be detriment-al, as being ineonveniently in the way when the bed is depressed by the weight of a body; and the object of my improvement is therefore, first, to remove this objection, and to this end I employ pivotal supporting-braces arranged diagonallyv and secured to the end sills of the main frame, thus leaving the main frame entirely open and removing all impediments to the free vertical resiliency ofthe web.

A further objection to the use of the bedbottom as formerly constructed lay in the ixed and unvariable resiliency of the bed-bottom, which was not adjustable to the variable weights of individuals. This difficulty, also, I overcome in theA present invention by rendering the pivotalengagement ot' the supporting-braces which uphold the movable side rails adjustable in a vertical plane. By this means the pivotal angle of said braces in relation tothe web and side rails may be adj usted so that a greater or less vertical displacement of the bed-bottom will compel a greater or less horizontal expansion of the elastic web,thereby increasing or diminishing the resistance, as required.

The constructive features of my invention are fully illustrated in the accompanying drawings, in which- (No model.)

Figure 1 isa plan view of the bed complete; Fig. 2, an end 'view of the bed; and Fig. 3ex hibits a crosssectional view ofthe bed.

Referring now to the drawings, A A B B' designate, respectively, the side and end sills constituting the main supporting-frame ofthe bed. v

c b designate the fixed elevated head and foot rails.

c c designate the movable side rails, and C the elastic web, secured in the manner pointed out in my previous patent.

It will be observed that the main frame is rectangular in form and entirely open, having no cross-braces intervening between the head and foot. rlhe side rails are supported, repectively, by braces D D, preferably metal strips, secured at one end pivotally by a screw to the inside of the movable side rails, c c', and at the other end by movable bolts e c to connecting-bars f f, (preferably of mctal,`) which connect the head and foot rails to the head and foot sills, respectively. rIlhe connecting-bars f j' are pierced with two or more apertures, g g, as maybe desired, in vertical series, through which the braces D D may be bolted tothe connecting-bars. It will be observed that the pivotal angle of the braces D D with the side rails, c c', will be greater or less, as the connection between the braces and the connecting-bars is made at the apertures nearest the sills or the head or foot rails, and a greater or less horizontal outward movement of the side rails obtained, as may be desired. It will also be readily seen that the adjustment may be different upon the opposite sides of the bed, if desired, so as to accommodate the bed to persons of different weights when it is to be occupied by two persons.

The side rails are provided with links or chains h h, to prevent too great vertical displacement, as described in my former patent. For the braces D D wooden blocks or boards may be substituted, if desired.

Having fully described my invention, I claim and desire to secure by Letters Datent of the United Statesl.
